SHUTTLE FOR LOOIVIS.

SPECIFICATION forming part of Letters Patent No. 669,504, dated March12, 1901.

Application filed. October 14,1899. Serial No. 733,626. (No model.)

. To all whom it may concern:

Be it known that I, JOHN C. BRYAN, a citizen of the United States,residing at Augusta, in the county of Richmond and State of Georgia,have invented a new and useful Shuttle for Looms, of which the followingis a specification.

This invention relates to loom shuttles; and the object of the same isto provide simple and effective means for removably receiving andholdiuga carrier or bobbin and which is particularly adapted forconjoint operation with automatically-actuated feeding devices.

The invention consists in the construction and arrangement of parts,which will be more fully hereinafter described and claimed.

In the accompanying drawings, Figure l is perspective view of a shuttleembodying the features of the invention. Fig. 2 is a side elevationthereof looking toward the self-threading construction. Fig. 3 is atransverse vertical section on the line 4. 4: of Fig. 2. Fig. 4 is alongitudinal vertical section, on an enlarged scale, taken in the planeof the line 5 5 of Fig. 3.

Similar numerals of reference are employed to indicate correspondingparts in the several views.

The numeral 1 designates a shuttle-body, which, as usual, is preferablyconstructed of wood, but in thisinstance has the opposite extremities 2and 3 similarly tapered and each provided with a metallic nose 4,comprising a shank 5, as shown by Fig. 4., fastened by a pin 6 toprevent it from working loose and also to strengthen the shuttle. Acarrier or bobbin slot 5 is cut through the body 1 in a horizontal planecompletely from one side to the other, and the top and bottom walls 6and 7 are completely closed, with one exception, which will be presentlyexplained. Adjacent one end wall of the slot 5 and projecting into thelatter are carrier or bobbin holding devices which comprise a movablejaw 8 and a fixed jaw 9. The movable jaw 8 has a shank 10, which isslightly bowed and movably seated in a recess 11 in the adjacent portionof the body 1, said recess continuing into a slot 12, which extendsthrough the bottom wall 7 and permits aT-head 13 to be disposed inmovable relation thereto and project upwardly into the slot 5. The shank10 is movably held in the recess 11 by a screw-rod 1 L, removablysecured to a nut 15 at the opposite side of the shuttle-body, and closesa cavity or seat 16, in which a coiled spring 17 is located andsurroundsa portion of the said rod 14, which acts to draw the shank 1Oclosely into the recess 11, but permits the movable jaw to havesufficient movement to serve its function. The jaw 8 ofitself isresilient, but offers a stiff resistance, which without reduction by themore sensitive nature of the spring 17 exerted thereon renders the samefree to autom atically receive the head of a carrier or bobbin, whichwill be under the pressure of feeding mechanism of sufficient stress toovercome the resistance that may be offered by the normal adjustment ofthe said jaw. The T-head is form ed with opposite convex rounded ends18, regularly merging into a central concaved seat 19, the latter beingof a length about corresponding to that portion of the cylindricalsurface of the head of the carrier or bobbin that rests therein, and theopposite curved ends 18 provide for an easy riding movement of thecarrier or bobbin head into and from the seat 19. The fixed jaw 9consists of a securing plate or member 20, having an angular supportingmember 21, with an inturned flange 22, which is normally disposed overand in line with the working edge of the T-head 13 and has a centralconcaved seat 23 and opposite rounded ends 24:. The plate or member 20is attached to the end wall of the slot 5 adjacent the position of themovable jaw 8, and the support 21 rests against the top wall 6, and bythis means a portion of the shuttle which is ordinarily weakened ismaterially strengthened and splitting or fracture at said point avoided.

Having thus described the invention, what is claimed as new is 1. In ashuttle for looms, the combination of a shuttle-body having a carrier orbobbin slot entirely therethrough from one side to the other, and meansfor holding a carrier or bobbin in said slot consisting of a fixed jawhaving an angular supporting member with a terminal inturned flange, anda yielding jaw with an inwardly-directed T-head and having a shankmovably located in the body of the shuttle, the inner edge of the saidT- head being in alinement with the edge of the inturned flange of theother jaw.

2. In a shuttle for looms, the combination of a body having a slotextending entirely therethrough from side to side for the reception ordischarge of a carrier or bobbin, and means for holding the bobbinsuspended within the said slot consisting of oppositelydisposed fixedand yielding jaws, the fixed jaw having an angular supporting memberwith a terminal inturned transversely-extending flange, and the yieldingjaw provided with an inwardly-directed transversely-ex- JOHN C.
